Kit Operation
After the TLV320AIC33EVM-PDK software installation (described in Section 6.2 ) is complete, evaluation
and development with the TLV320AIC33 can begin.
When the program first starts up, a small window ( Figure 3 ) appears that gives two choices for the control
interface: I
2
C or SPI. Click on the interface that will be used by the EVM, as selected by the jumper
settings detailed in Table 5 .
Figure 3. Interface Selection Window
If the I
2
C interface is selected, a second window then appears which allows for selecting the address of
the TLV320AIC33. This window (see Figure 4 ) has two checkboxes for setting the state of A0 and A1.
Note that this address should correspond to the jumper settings selected as described in Table 5 .

2
C Address Selection Window
Figure 2 illustrates the indicators and controls near the top of the screen, and a large tabbed interface
below. This section will discuss the controls above this tabbed section.
At the top left of the screen is an Interface indicator. This indicator shows which interface is selected for
controlling the TLV320AIC33 , either I
2
C or SPI; it is lit after the program begins.
To the right of the Interface indicator is a group box called Firmware. This box indicates where the
firmware being used is operating from—in this release, the firmware is on the USB-MODEVM, so you
should see USB-MODEVM in the box labeled Located On:. The version of the firmware appears in the
Version box below this.
